Seagate Analysis Reveals Arduous Disks Have Decrease CO2 Emissions than SSDs

As per reviews, international carbon emissions have elevated from round 25 billion tonnes in 2001 to shut to 38 billion tonnes in 2023 – a whopping 52% improve because the flip of the century. The identical report says that the CO2 emissions haven’t peaked but, which implies there’s extra to comply with. 

Whereas solely industrial-level laws can deliver a couple of noticeable change, Seagate has shared important analysis that claims arduous drives are higher than SSDs in the case of carbon emissions in mild of accelerating knowledge middle wants. 

With AI rising at never-before-seen speeds, the demand for knowledge facilities will improve by a whopping 165% by 2030, which can in the end result in extra carbon emissions. Nevertheless, utilizing arduous drives quite than SSDs can lower down the emissions. Right here’s what the analysis discovered:

Storage Media	Embodied Carbon by product (Kg CO²)	Embodied Carbon per TB (CO²/TB)	Embodied Carbon per TB per 12 months (CO²/TB/12 months)
Arduous Drives	29.7	<1	<0.2
SSD	4,915	160	32
LTO Tape	48	2.66	<0.6

Because the figures recommend, SSDs are a no-go for the setting, emitting the very best embodied carbon by-product, per TB, and CO²/TB/yr. On the flip facet, arduous drives are probably the most environmentally pleasant.

The report additionally shares three strategic pillars for a sustainable future:

• Constructing energy-efficient tech like HVAC techniques and liquid/immersion cooling applied sciences can scale back CO2 emissions and vitality consumption.
• Reusing, repairing, recycling, and refurbishing storage gear can improve its lifespan and assist scale back e-waste.
• Collaboration throughout the complete worth chain with shared accountability amongst suppliers, distributors, and repair suppliers.

The Actual-Life Drawback

Whereas it appears fairly simple in idea, switching to arduous drives is tougher than you suppose. For starters, HDD storage gadgets are gradual since they use magnetic spinning disks to learn and write knowledge. 

Every time a knowledge request is made, the disk must spin to the precise place to have the ability to retrieve that knowledge, which slows down the entire course of. This isn’t best for AI instruments and merchandise, which depend on on the spot knowledge retrievals. Plus, with HDDs, knowledge can get scattered over time in addition to being extra susceptible to bodily put on and tear. 

SSDs, alternatively, use flash reminiscence with none transferring components, permitting on the spot knowledge retrievals. Additionally they use parallel studying and writing strategies, which means the method is sort of on the spot.

On the finish of the day, it’s a easy query: Why would tech firms change to a slower and outdated storage methodology? Would the truth that it results in decrease CO2 emission be sufficient to make the change?

Properly, it wouldn’t take a genius to guess that the reply is an enormous fats NO. OpenAI, Microsoft, Google, or DeepSeek gained’t simply get up tomorrow, learn the Seagate report, and change into environmentalists. A extra sensible resolution is to innovate a greater SSD prototype that emits much less CO2 with out compromising its advantages.

Seagate is already engaged on bringing NVMe expertise to arduous drives, which makes use of the PCIe interface for sooner knowledge transfers. This additionally permits direct and fast knowledge entry required for tech-heavy AI industries. NVMe additionally permits direct knowledge entry from storage to GPU, with none involvement of the CPU, main to raised latency.

Nevertheless, a right away resolution is, sadly, not in sight proper now, and we’d nonetheless be 2-3 years away from a significant breakthrough.
